01 WHAT IS PCBA printed circuit board (PCB)mechanically supports and electricallyconnects electronic components usingconductive tracks, pads and otherfeatures etched from copper sheetslaminated onto a non-conductivesubstrate. Components are generallysoldered on the PCB.--------wikiPCBWAY.COM

03 PCB manufacturing processDry film/ image transferDry film is a kind of polymercompound, which can producepolymerization after irradiation ofultraviolet rays. Then will form astable substance attached to theboard surface, so as to achievethe function of blocking platingand etching.PCBWAY.COM
03 PCB manufacturing processEtching is using chemical way to removeEtchingunwanted copper from pcb. Then the circuit isappeared, usually acid is used to etch . �进行更改 �、颜色、行距等进行修改Brown OxideMaking chemical oxidation of copper surfacesto generate oxides on the surface to increaseroughness. It will improve adhesion.PCBWAY.COM
03 PCB manufacturing processAOIAutomated optical inspection (AOI) is an automated visualinspection of printed circuit board manufacture where a cameraautonomously scans the device under test for both catastrophicfailure (such as missing component) and quality defects.It is commonly used in the manufacturing process because it is anon-contact test method. This guarantees the high reliability ofMulti-CB multilayer circuit boards.PCBWAY.COM
03 PCB manufacturing processElectronic test/probe testCombine Automatic optical alignment system and the traditional flyingneedle machine together , with the help of image-processing softwareand flying-pin-only cameras, flying probe test is easier and moreaccurate.The layout is analysed according to the pcb file for short circuits andinterruptions. This is important because only the E-test detectsincorrect and broken conductors. And the detected defective circuitboard will be marked.Check https://www.youtube.com/watch?v 3wtkQx66mxkPCBWAY.COM
